code to get the status

#  connect to your SSID
print("Try to connect to SSID:", os.getenv('WIFI_SSID'))

url = "http://192.168.8.158:8000/status"
while True:
    try:
        response = requests.get(url)
        response_as_json = response.json()
        print()

code to post my data

# 
import ssl
import wifi
import socketpool
import adafruit_requests
import microcontroller
import time

#  connect to your SSID
print("Try to connect to SSID:", os.getenv('WIFI_SSID'))
wifi.radio.connect(os.getenv('WIFI_SSID'), os.getenv('WIFI_PWD'))

fake_data = { "device": "chest", "temperature": 22, "humidity": 60, "pressure": 1100, "gas": 1340 }
response = requests.post(url, data=fake_data)
print()
print(response.status_code)
print()
#

and this fails with:

Try to connect to SSID: GLTC2.4
My IP address is 192.168.8.123
Traceback (most recent call last):
  File "adafruit_requests.py", line 534, in _get_socket
OSError: [Errno 104] ECONNRESET

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "code.py", line 19, in <module>
  File "adafruit_requests.py", line 732, in post
  File "adafruit_requests.py", line 717, in request
  File "adafruit_requests.py", line 668, in request
  File "adafruit_requests.py", line 515, in _get_socket
RuntimeError: Sending request failed```
#

I made some progress.
my fastapi was answering "307 Temporary Redirect" because the POST url did not ended with a "/" character.
Now I have 422 Unprocessable Entity so I guess I need to figure out how to properly send json data

#

🎉 it worked.
Here is the code to send json data

import ssl
import wifi
import socketpool
import adafruit_requests
import microcontroller
import time
import json

#  connect to your SSID
print("Try to connect to SSID:", os.getenv('WIFI_SSID'))
wifi.radio.connect(os.getenv('WIFI_SSID'), os.getenv('WIFI_PWD'))
print("My IP address is", wifi.radio.ipv4_address)

pool = socketpool.SocketPool(wifi.radio)
requests = adafruit_requests.Session(pool, ssl.create_default_context())

url = "http://192.168.8.158:8000/sensor_values/"
fake_data = json.dumps({ "device": "chest", "temperature": 22, "humidity": 60, "pressure": 1100, "gas": 1340 })
headers = { 'accept': 'application/json' }
response = requests.post(url, data=fake_data, headers=headers)
print()
print(response.status_code)
print()

All this is part of a conference I'll give next week at Devoxx UK and I'll post the repository with all the code right after

So, your issue is completely resolved?
